Researchers at the Dalian Institute of Chemical Physics have developed an innovative aqueous battery that reaches a specific capability of 840 Ah/L and an energy density of 1200 Wh/L, improving both security and energy performance in battery technology. Credit: DICPTraditional lithium-ion batteries, while offering high energy density, have actually jeopardized safety because they use flammable organic electrolytes.Aqueous batteries use water as the solvent for electrolytes, significantly improving the safety of the batteries.” This study provides a brand-new concept for the design of high-energy-density liquid batteries, and may expand the aqueous batteries application in power batteries field,” stated Prof. Li.Reference: “Reversible multielectron transfer I −/ IO3 − cathode enabled by a hetero-halogen electrolyte for high-energy-density liquid batteries” by Congxin Xie, Chao Wang, Yue Xu, Tianyu Li, Qiang Fu and Xianfeng Li, 23 April 2024, Nature Energy.DOI: 10.1038/ s41560-024-01515-9.
